The quick-dry synthetic insulation and efficient warmth-to-weight ratio of the Solar 2 Sleeping Bag brings a generous mix of camping activities into play. As practical for late season forays into the hills as for summer nights out with the family, it comes with 20D polyester construction for easy packability, an internal 3D collar to keep the drafts out and an angled foot box to keep your feet warm without restricting movement. To make things even more user-friendly, it also features a highly flexible three-quarter length YKK coiled zip with insulating baffle and anti-snag guard, plus a secure internal stash pocket and a handy stuff sack.
